Description

This is an 8 count bundle of a test revision of the AIOB, which is not fully functioning due to a design flaw.

What works:

• Audio In / Out over USB
• PTT over COM port or Automatic VOX PTT (Depending on Firmware)

What doesnt work:

• Serial TX Pad for cat control or programming of a radio

Note: By removing two resistors you can use the tiny 5v rtxd pad for 3.3v operation, though this modification is difficult and the pad is very small. A couple of boards already have this modification.

Sold AS-IS, all sales final.
